Your inverter sounds like it has the ability to power two CCFL tubes, which is unusual. Most CCFL inverters are really cheap devices that would overheat or improperly power more than one CCFL. I'll assume that it does have two outputs and is designed to do that. If you are not *sure*, then contact the place you bought your CCFL's and inverter.

If the inverter is 12V powered, you need to have the switch on the INPUT side of the inverter. So, you need to switch the 12VDC power going to the inverter, not the high voltage output from the inverter.

Now, I don't know what kind of switch you bought. The switch might by double throw or single throw, and it might be single pole or double pole. Look here for an explanation of throws and poles.

Basically, you could get by with a cheap single throw single pole switch. You would have the inverter's ground wire (black) connected directly to the black wire of a standard 4-wire PC molex plug. Then, connect the YELLOW wire of the PC molex plug (12VDC) to one connecter on a single throw single pole switch. Then, connect the inverter's other input wire (red?) to the other connector on the switch.

At this point, the switch controls whether the inverter gets power or not. The inverter is always connected to ground, but the switch interrupts the power coming from the 12VDC line from your computer.

Is that what you were looking for?
